BrightScript uses the following scoping rules:

- Global variables are not supported; however, there is a single hard-coded global variable (“global”) that is an interface to the [global BrightScript object](docId\:nSjXffR7OlFgDWgjFEbMe), which contains all global library functions.
- Functions declared with the `Function` statement are global in scope; however, if the function is anonymous, it will still be local in scope.
- Local variables exist within the function scope. If a function calls another function, that new function has its own scope.
- Labels exist within the function scope.
- Block statements such as `For / End For` and `While / End While` do not create a separate scope.
